INVENTORS ARLEEN F AC AND HUBERT VAN BREE ATTORNEYS Patented F eb. 8,1938 UNITED STATES PATENT OFFICE This invention appertains toself-contained electrically driven clippers, and more particularly toclippers of the type having removable.

unitary cutting assemblies.

It is now customary to provide electrically driven hair clippers andclippers for giving dry shaves. Some clippers have cutting assemblies(that is, assemblies of fixed and movable blades) which may be attachedto or detached from the body portion of the clipper.

One of the primary objects of our invention is to provide a novel meansfor connecting the cutting assembly with the body of the clipper,whereby a strong and sturdy construction will be had, and wherebydifferent types of cutting assemblies, such as for hair cutting or dryshaves, can be quickly and expeditiously connected with or detached fromsaid body portion.

Another salient object of our invention is to provide spaced postsrigidly mounted on the cutting assembly for snug insertion in socketsformed in the body, so that all lateral shifting of the assemblyrelative to the body will be prevented, and whereby no difiiculty willbe encountered by the operator in associating the assembly with thebody.

A further important object of our invention is the provision of novelmeans associated with the body for releasably engaging said posts,whereby accidental displacement of the posts and the as sembly from thebody will be prevented.

A still further object of our invention is the provision of a simple andeffective means including a thumb-operated lever for releasing the postsfrom their holding means and for displac- "ing the cutting assembly fromthe body.

structed in accordance with our invention, parts thereof being shownbroken away and in section to illustrate structural details. I

Figure 2 is an enlarged, fragmentary transverse section through theclipper taken substanx tially on the line 2-2 of Figure 1, looking inthe direction of the arrows, illustrating the means for detachablyengaging the posts. Figure 3 is a fragmentary sectional view takensubstantially on the line 3-3 of Figure 1, looking in the direction ofthe arrows, illustrating the pivot for the operating lever. v

Figure 4 is a detail perspective view of the operating lever.

Referring to the drawing in detail, wherein similar reference charactersdesignate corresponding parts throughout-the several views, the letter Cgenerally indicates the clipper, which comprises a body portion I. Thisbody portion I can be made from any preferred materials and in anydesired shape, and forms the housing for the electric drive motor (notshown).

The forward end of the body portion I carries a head I having anangularly extending lower face I. Extending into the head 8 is thearmature shaft 8 of the motor for rapidly oscillating the actuatinglever 8. This lever 0 extends forwardly of the head I, for a purposewhich will be later setforth. The lower inclined face I of the head hasformed therein a pair of spaced sockets ill and Ii, the p rp se of whichwill be hereinafter more fully set forth.

The cutting assembly It comprises a fixed blade I! and a movable-bladel4. 'Ihe movable blade I4 is resiliently urged toward the stationaryblade i2, and has formed therein a socket for receiving the forwardlyextended end of the oscillating lever '8. The rear edge of thestationary cutting blade I! has formed thereon a rearwardly directedplate It, which is adapted to lie close up against a portion of theinclined face I of the head I.

This inclined surface 1 has formed therein a longitudinally extendinggroove II, the purpose of which will be hereinafter more fully setforth. This plate II has rigidly secured thereon a pair of upstandingposts or studs ii and II, which are adapted to be snugly received withinthe sockets II and ii. v

vAs illustrated, screws I! extend through the plate l5 and into thestuds or posts l1 and It for firmly connecting the posts or studs to theplate. These screws II and the posts can be utilized for holding theresilient plate 2| for the movable blade It in place. If preferred, theouter ends of the posts can be tapered for facilitating the insertion ofthe posts in sockets and for another purpose, which will also be laterset forth.

Directly inward of the tapered ends, the posts have formed thereinannular grooves 2i, which constitute keeper sockets for latch pins 22.The latch pins 22 are normally urged into the sockets II by means ofsprings 23. The springs 23 are confined in place by removable threadedplugs ,carriedbythesides of theheadi. The plugs 24 form a convenientmeans for permitting the assembly of the pins 22 and springs in thehead.

Arranged within the groove I6 is a releasing lever 25. This releasinglever 25 has formed therein intermediate its ends an opening 26 for thereception of a holding screw 21, which is threaded in a socket 28 formedin the head 6. The screw 21 has a loose fit in the opening 26, wherebythe lever will be free to rock on the said screw.

The sides of the lever have formed thereon inturned wings 29 adjacent tothe opening 26, and these wings engage the head and form a fulcrum forthe lever. The forward end of the lever extends under the plate I5between the studs or posts Ill and II, and by pressing on the outer endof the lever, the lever will forcibly engage the plate of the cuttingassembly, and thus move the posts outwardly of the sockets, releasingthe same from the spring-pressed pins 22. The rear end of the lever canbe provided with an inwardly directed guide tongue 30 for movement intoa guide socket 3! formed inthe head i.

In use of our improved clipper, when it is desired to associate acutting assembly with the body portion of the clipper, it is merelynecessary to insertthe posts l1 and I8 into the sockets l0 and II untilthe plate firmly engages the inclined face I. The tapered portions ofthe studs or posts l1 and I8 permit the ready springing back of thespring-pressed pins 22, and, obviously, when the posts are in theirfully inserted position the spring-pressed pins will engage in thegrooves 2| and hold the posts and consequently the cutting assemblyagainst accidental displacement.

As stated, by merely pressing on the outer end of the lever 25, theposts can be forced outwardly of the sockets and past the spring-pressedpins.

By our construction, different types of hair cutting assemblies can bereadily associated with the head, and the cutting assemblies can beeasily and quickly cleaned. The studs form an ideal means for permittinga firm connection to be had between the body portion of the clipper andthe cutting assembly.

Obviously, a dry shaver cutting assembly can be associated with the body5, and thus the clipper can be of a universal character and used bothfor hair cutting and shaving.

Changes in details may be made without departing from the spirit or thescope of our invention, but what we claim as new is:

1. In a clipper, a body portion provided with a pair of spaced sockets,unitary cutting assembly for detachable association with the body, rigidposts carried by the cutting assembly for movement into and out of thesockets, releasable means carried by the body for engaging the posts tohold the posts against accidental displacement, and manually actuatedmeans having a portion disposed between the body and the cutter assemblyfor forcibly moving the assembly and the posts away from thebody uponactuation of said means.

2. In a clipper, a body portion having a forwardly extending headprovided with an inclined lower surface, a unitary cutting assembly,rigid posts carried by said cutting assembly, the head having socketsformed therein extending inwardly from said inclined surface forreceiving the posts, releasable means engaging said posts for holdingthe same against accidental displacement in the sockets, and a manuallyoperated lever rockably mounted on said head having its inner endextending between the cutting assembly and said face adjacent to theposts.

3. In a clipper, a body portion having a forwardly extending headprovided with an inclined lower surface and sockets extending inwardlyfrom said surface, a unitary cutting assembly including a stationaryblade and a movable blade, a rearwardly extending plate on thestationary blade adapted to fit against said inclined face, rigid postscarried by said plate for insertion in said sockets, spring-pressed pinscarried by the head normally urged in the sockets, said :posts havingkeeper recesses for receiving the pins when the posts are fully insertedin said sockets. and manually actuated means for moving the cuttingassembly and the posts away from the head, said means including apivotally mounted lever having its forwardend extendin between the plateand said inclined surface.

4.-In a clipper, a body portion having a forwardly extending headprovided with an inclined lower surface,,a pair of sockets extendinginwardly from said surface, and a groove located between the sockets, acutting assembly including a stationary blade and a movable blade, arearwardly directed plate formed on the stationary blade adapted toengage said inclined face and overlie a portion of said groove, a pairof rigid posts carried by the plate for reception in said sockets, saidposts being provided with annular grooves, spring-pressed pins carriedby the head for engagement in said grooves when the posts are fullyinserted in said sockets, an operating lever having an opening arrangedbetween the ends thereof and inwardly directed fulcrum wings on eachside of said opening, a pin loosely extending through said opening andinto the head, the forward end of the lever being disposed in saidgroove between the plate and the inclined surface and intermediate saidposts, the rear end of the lever extending beyond the plate and having afinger manipulating surface thereon.
